Hi everyone,
I’m testing Keycloak 18.0.0 with Quarkus.
I am impressed by the work done: congratulations to all the people working on the project 
It’s much easier to set up and configure
I have seen this post:
In which dasniko explains there is no “domain” etc.
But I’m not sure I’m in the right direction to have 2 nodes (active/active or active/passive).
My need is simple:
- worst case: in case of failure with my node 1, I would like to be up because of the node 2
- nice case: to have an active/active cluster
What I did:
- VM 1/3: I configured Nginx as reverse proxy + load balancer
- VM 2/3: I installed/configured Keycloak 18.0.0
- VM 3/3: I installed/configured Keycloak 18.0.0
- my database is PostgreSQL:
- master in VM 2/3
- slave in VM 3/3
If I stop Keycloak in the VM 2/3, it seems it works: Nginx load balance to VM 3/3
But I have doubts…
Is it the good solution / approach?
How to deal with PostgreSQL database update?
For example should I configure spi-connections-jpa-default-migration-strategy:
- to ‘update’ on VM 2/3
- to ‘manual’ on VM 3/3
To avoid a conflict?
Is it possible to have an active / active system with this edition based on Quarkus ?
If yes, how?
Sorry maybe I mis a documentation or something somewhere…
But all documentations related to HA I found seems related to Wildfly 
Last question.
With the console in the previous versions, it was possible to deploy a theme directly to all nodes for example.
Is it possible with Quarkus?
Thank you very much
